Using 7 1/2 / 3/4 = 60/6=10 interpret the meaning of the quotient in terms of the two fractions given

maks197457 [2]

Answer:

Here's what I get.

Step-by-step explanation:

$x = 7\frac{1}{2} \div \frac{3}{4}$

1. Convert the mixed number to an improper fraction

$x = \dfrac{15}{2} \div \dfrac{3}{4}$

2. Invert the proper fraction and change division to multiplication

$x = \dfrac{15}{2} \times \dfrac{4}{3}$

3. Multiply numerators and denominators

$x = \dfrac{60}{6}$

4. Divide the numerator and the denominator

$x = 10$

The quotient is what you get after you invert the denominator in Step 2 and then multiply the two fractions in Step 3.
