Question

3/4 -2 4/5 I NEED HELP ASAP PLS HELP ME

Answer 1

Answer:

-41/20

Step-by-step explanation:

Hi there!

From the question, I believe you’re asking $\frac{3}{4}$ - $2 \frac{4}{5}$

First, put the whole number 2 back into the fraction to create an improper fraction.

This would become $\frac{14}{5}$. Now, we have to find a common denominator between the two fractions. Both 4 and 5 can go into 20, so that will be our common denominator. To turn $\frac{3}{4}$ into a fraction with a denominator of 20, we have to multiply both the numerator and denominator by 5. $\frac{3}{4}$ becomes $\frac{15}{20}$. We do the same thing for $\frac{14}{5}$ except we multiply the numerator and denominator by 4. We end up with $\frac{56}{20}$. Now we just have to subtract!

$\frac{15}{20} - \frac{56}{20}$ leaves us with $- \frac{41}{20}$ , which can’t be simplified any further.

Answer 2

Answer:

-2.05, in fraction form it would be -2 1/20
