7 1/5 times 49 7/5 equivalent to 49

Answers

Answer 1

Step-by-step explanation:

7 1/5 × 49 7/5 = 49

convert mixed numbers into improper fractions (whole number × denominator + numerator)

7 × 5 + 1 = 36

49 × 5 + 7 = 252

36/5 × 252/5 = 49

All fractions must have a common denominator

49 × 5 = 245

36/5 × 252/5 = 245/5

Add numerators

36 + 252 = 288

288/5 = 245/5

57 3/5 = 49

These do not equal each other according to my calculations. Is the problem written correctly? Or did I misinterpret a given number?

You have been asked to build a scale model of your school out of toothpicks. Imagine your school is 30 feet tall. Your scale is 1 ft:1.26 cm.

Answers

Answer:

The model will be 6 toothpicks tall.

Step-by-step explanation:

your school is 30 feet tall and 1 feet is 1.26 cm, so you would most likely multiply 30 and 1.26 in order to  get the height of the scale model which is 37.8 cm. Each toothpick is 6.3 cm, you would take 37.8 and divide it by 6.3 to get the number of toothpicks So, for you to build the school, it would be 6 tp tall.

Aisha had 2 gallons of paint. She used 4 /5 of the first gallon and 1/4 of the second gallon.

How many gallons were left over?



A: 15​ gallon

B: 34 gallon

C: 1920 gallon

D: 1120 gallons

Answers

Answer:

19/20

Step-by-step explanation:

you spelled them wrong  A is 1/5 B is 3/4 C is 19/20 D is 11/20 but C is the right answer

The leftover gallon of paint she has now is C: 19/20 gallon

What is a fraction?

A fraction is written in the form of p/q, where q ≠ 0.

Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.

Given, Aisha had 2 gallons of paint.

She used 4 /5 of the first gallon and 1/4 of the second gallon.

∴ The amount of leftover paint is 2 - (4/5 + 1/4).

= 2 - (16 + 5)/20.

= 2 - 21/20.

= (40 - 21)/20.

= 19/20.

Step-by-step explanation:

Lynn is making custom bricks. She combines 39 pounds of water and 48 pounds of brick dust in a mixing bucket. She spills 13 pounds of the mixture while stirring the contents. The mixture is then poured into small dirt holes to make bricks. Each brick requires 7 pounds of mixture, and the leftover mixture is washed out of the mixing bucket.
What is the greatest number of bricks Lynn can make?
bricks
How many pounds of mixture will be washed out of the bucket if Lynn makes the greatest number of bricks?

Answers

Lynn mixes 39 pounds of water with 48 pounds of brick dust, so the mixture has a total weight of 39 + 48 = 87 pounds.

13 pounds are spilled during mixing, so she's left with 87 - 13 = 74 pounds to turn into bricks.

7 pounds are needed for 1 brick, so she can make 10 bricks because 7 • 10 = 70 and 7 • 11 = 77, and 70 < 74 < 77.

If she uses the mixture to make 10 bricks, she uses up 70 pounds of it, which leaves 4 pounds to be washed out.

Round 2.500 g to the nearest whole gram

Answers

Answer:

Step-by-step explanation:

3 grams.

Answer:

3 grams

Step-by-step explanation:

Whole numbers do not include any decimals. They include numbers such as 1, 2, 3, 4, 5...

2.500 g is equal to 2 and a half grams, which we know is between 2 and 3 grams. This means that the nearest whole gram has to be 2 or 3.

When rounding, look at the digit to the right of the digit being rounded, and if it is 5 or more, round up. If it is 4 or less keep the digit same.

Here, 5 is the digit to the right of 2, so we round up to 3 grams.
