Answer:

Carlos is correct. If the numerators are the same, the fraction with the lesser denominator will be greater.

Step-by-step explanation:

I'll answer this question using the following illustration.

Let a fraction be:

[tex]\frac{1}{2}[/tex]

and another fraction

[tex]\frac{1}{4}[/tex]

Both numerators are 1. In other words, they are equal

When you compare the denominator, 2 and 4, the fraction with lesser denominator is greater

This is so because:

[tex]\frac{1}{2} = 0.5[/tex]

[tex]\frac{1}{4} = 0.25[/tex]

By comparison

[tex]0.5 > 0.25[/tex]

This analysis can  be used for any fraction as long as they have the same numerator

Hence, option A answers the question

Answer:

x= 50

Step-by-step explanation:

7/x = 14/100

14x = 700

x = 50

the reason behind my calculations were to get the same ratios and because they gave us percentage and the actual number, we can set them; 14 percent 14/100, however, the 7/x is because we don't know the 100 percent of the coins which is what we look for. Therefore, you cross multiply and get x.

Answer:

The red car is faster compared to the blue car.

The red car is faster by 5.5 feet than the blue car.

Step-by-step explanation:

The objective is to find which car is  faster and by how much

Given that:

The blue car traveled 54 feet in 4 seconds; &

The red car traveled 38 feet in 2 seconds.

Let us determine the number of feet traveled in each second for both cases.

For the blue car:

In 1 second, the car will travel = 54/4 feet

In 1 second, the car will travel = 13.5 feet

For the red car:

In 1 second, the car will travel = 38/2 feet

In 1 second, the car will travel = 19 feet

Thus, the red car is faster compared to the blue car.

The distance at which the red car is faster than the blue car = 19 feet - 13.5 feet

= 5.5 feet

The price of gallons as per number of gallons.

1 gallon to $1.50

30 gallons to $45.00

$1.00 to 2/3 gallon

Finding cost of gallons

Accoring to the question, the price of two gallons of vinegar is $3.00. A chef need fifteen gallons of vinegar to make pickles.

As we know the price of two gallons of vinegar, we can find out price for any amount of vinegar by applying cross multiplication method.

Let's find out price of different amounts of gallons

The cost of two gallons of vinegar = $3.00

So, the cost of one gallon of vinegar = $3.00/2 = $1.50.

we find out that cost of one gallon of vinegar is $1.50.

Let's find the cost of other amount of gallons.

The cost of four gallons = ?

we know the cost of one gallon is $1.50, so the cost of four gallons is $1.50 × 4 = $6.00

This is how we can find out cost of other amount of gallons by multiplying number of gallons by the price of one gallon.

Step-by-step explanation:

The solution of the given equation would be 8.

An equation is an expression that shows the relationship between two or more numbers and variables.

A mathematical equation is a statement with two equal sides and an equal sign in between.

A system of equations is two or more equations that can be solved to get a unique solution and the power of the equation must be in one degree.

We are given the equation as;

6f = 48

We have to Complete each statement.

First, divide by 6 into both sides of the equation.

f = 48/6
