Divide: 5 1/2 divided by 2 1/2 =

To determine which expression is the largest, you can consider each ratio or fraction and evaluate its decimal equivalent or compare its relative value. Each expression lists a ratio of 1 to another number, so essentially, we're looking at fractions:

• A
• B
• C
• D

Among these, the largest fraction is the one with the smallest denominator, because the whole (1 in this case) is divided into fewer parts, making each part larger. Therefore, the largest fraction, and thus the largest expression, is: C 1:2

To add the fractions ​ and , we will need a common denominator. The least common denominator between 8 and 2 is 8.

Convert 12​ to a fraction with 8 as the denominator:

= =

Now add the two fractions:

​+ = =

The result, ​, is an improper fraction, which can be converted into a mixed number:

=

Thus, the answer is A 1 1/8.

Calculate the difference in the cost per gallon between the two prices and then multiply that difference by the number of gallons he purchased.

Difference in cost per gallon:

2.26−2.14=0.12dollarspergallon

Number of gallons purchased:

15.7gallons

Total savings:

0.12×15.7=1.884

Rounding to the nearest cent, the total savings is approximately: $1.88

Therefore, the man saved by going to the less expensive station is: D $1.88

To solve this proportion, we set up the ratio of the given terms equal to the ratio of the unknown term:

=

Now, we cross multiply:

125×𝑋=5×75

125𝑋=375

Now, solve for X by dividing both sides by 125:

𝑋 == 3

So, the value of X is 3.

Therefore, the correct answer is: C X= 3
