Ten children will share a bag of candy consisting of 78 pieces. Every child will receive the same number of pieces. What is the greatest number of pieces of candy each child can receive?
(This is division and has a reminder!)
Answer:
78÷10=7.8, so roughly 7-8 pieces of candy per child.
Answer:
The max that each chiles can receive is 7 pieces. This is because when you have a remainder in this type of equation that cannot pass it out without using fractions you keep it away.

Answer:
70
Step-by-step explanation:
The % itself stands for a ratio of 100, so 70% would be 70/100
Answer:
70/100
Step-by-step explanation:
This is because if you break down a percantage, it is just a fraction or decimal. The numerator is 70 because 70/100 = 0.7
0.7 is just the decimal form of the percent "70%"

he went 13 units right instead of 12
Step-by-step explanation:
Can someone help me with this
Step-by-step explanation:
Look at the top problem first.
There is only one place where you see both numbers of the ratio. It is the last column. 56/14 = 4. That means that every number on the top line has to be 4 times the number below it.
14/3.5
28/7
42/10.5
Now look at the second problem. You have 44.4 and 1332.
1332/44.4 = 30
The bottom line is 30 times greater than the line above.
88.8/2664
22.2/666
11.1/333

Step-by-step explanation:
Look at the word “permission.” a) What is the ratio of consonants to vowels? b) What fraction of the letters are consonants? c) What percent of the letters are vowels. please do all steps giving brain list
Answer:
6:4 or 3:2
6/10 are consonants
40%
Step-by-step explanation:
A) count the numbers of consonants and vowels. There are 6 consonants and 4 vowels so the ration is 6:4. If you're simplifying, you divide both sides by 2 to get 3:2
B) Count the total letters. There are 6 consonants and 10 total letters so the fraction is 6/10 because 6 put of 10 are consonants.
C) 4. x
- = 10x = 4(100)
10. 100. 10x = 400
- -
10. 10
x= 40
You divide 10 by 10 to get x alone and then divide 400 by ten.

Tonya works 60 hours in 3 weeks. Select ALL the true statements OR YOU WILL FAIL THE GRADE.
A. Tonya works 100 hours in 4 weeks.
B. Tonya works 140 hours in 7 weeks.
C. Tonya works 20 hours a week.
D. Tonya works 5 hours a day, 5 days a week.
E. At this rate, Tonya will work 240 hours in 16 weeks
Answer: b & c
Step-by-step explanation:
first i found how many hours tonya works in one week which was 20. i got that by dividing 60 by 3. then that set me up for finding the answer to the other problems as well. 60+20=80 so a wouldn’t have worked. 5x5 is 25 and she only worked 20 hours a week. and she would’ve worked 320 hours in 16 weeks, not 240. hope this helps!! :)
Answer:
B and C
Step-by-step explanation:
This problem is pretty simple if you know how to do some multiplication. First, we should figure out how many hours she works per week. You can figure this out by dividing 60 by 3. This gets us 20.
Now that we know how many hours she works each week, we can figure out the rest of the problems.
A is incorrect because 4 x 20 =80.
B is correct because 7 x 20 is 140.
C is correct because we did this problem earlier to solve the others.
D is in correct because 5 x 5 = 25, which does not equal 20.
E is incorrect because 16 x 20 = 320
