Question

What is ; 3 3/4 - 2 1/5 thanks!

Answer 1

Answer:1 11/20 (I think)

Step-by-step explanation: First subtracting 3 - 2 gets you 1. so we keep that aside and do fractions. first, what do 4 and 5 have in common? They both can be turned to 20. 3/4 can be multiplied to 20 4x5(20) so we do 3x5=15 now you have 15/20. Hope this makes sense. now we do 1/5 to ?/20 5x4=20 1x4=4 so 15/20-4/20=11/20 11/20+1= 1 11/20

-Sorry if its too complicated

(undo ur answer if u trusted me before bc I messed up)

(its good now)

Answer 2

Answer:

1$\frac{11}{20}$

Step-by-step explanation:

3$\frac{3}{4}$ - 2$\frac{1}{5}$

Multiply 3 and 4 to get 12.

$\frac{12+3}{4} - \frac{2x5+1}{5}$

Add 12 and 3 to get 15.

$\frac{15}{4} - \frac{2x5+1}{5}$

Multiply 2 and 5 to get 10.

$\frac{15}{4}$ - $\frac{10+1}{5}$

Add 10 and 1 to get 11.

$\frac{15}{4} - \frac{11}{5}$

The least common multiple of 4 and 5 is 20. Convert $\frac{15}{4}$ and $\frac{11}{5}$ to fractions with denominator 20.

$\frac{75}{20} - \frac{44}{20}$

Since  $\frac{75}{20}$ and $\frac{44}{20}$ have the same denominator, subtract them by subtracting their numerators.

$\frac{75 - 44}{20}$

Subtract 44 from 75 to get 31.

$\frac{31}{20}$

Simplify

$\frac{31}{2^{2} x 5 }$ = $1\frac{11}{20}$

Hope it helps and have a great day! =D
