Question

What is the value of the expression 3 divided by 3/4? (It’s 4) Jane got 2 1/4 as the correct answer. How did she get that answer?

Answer 1

Answer:

see the explanation

Step-by-step explanation:

we have

$3:\frac{3}{4}$

Multiply in cross

$\frac{3*4}{3}=\frac{12}{3}=4$

Jane got 2 1/4 because she multiplied 3 by 3/4 instead of dividing 3 by 3/4.

so

$3(\frac{3}{4})=\frac{9}{4}= \frac{8}{4}+\frac{1}{4}=2\frac{1}{4}$
