Question

by what number should 1 3/4 be divided to get 2 1/2?

Answer 1

STEP 1: Define x

Let the number be x

.

STEP 2: Form the equation:

1 3/4 ÷ x = 2 1/2

...........................................................................................

STEP 3: Solve x:

1 3/4 ÷ x = 2 1/2

Change all fractions to improper fractions:

7/4 ÷ x = 5/2

Put it in single fraction:

7/(4x) = 5/2

cross-multiply:

5(4x) = 7(2)

Distribute 4 and 7:

20x = 14

Divide both sides by 16:

x = 14/20

Simplify:

x = 7/10

............................................................................................

Answer: the number is 7/10
