I need help pls help me

lutik1710 [3]

First Method:

Round $\frac{3}{5}$ to the closest integer, which is 1.

Round $\frac{3}{4}$ to the closest integer, which is also 1.

So 1 + 1 = 2.

Answer for method 1: 2

Second Method:

$\frac{3}{5}$ + $\frac{3}{4}$ = $\frac{3*4}{5*4} + \frac{3*5}{4*5} = \frac{12}{20}+\frac{15}{20}=\frac{27}{20}$

$\frac{27}{20}$ is around 1

Answer for method 2: 1

The closest answer is 1.

Ethan writes 2/3 of a page in 5/12 of a minute. How much time does it take him to write one page

Nataliya [291]

2/3 of a page in 5/12 of a minute

Multiply both fractions by 3/2

$\frac{2}{3} \times \frac{3}{2} = 1$

$\frac{5}{12} \times \frac{3}{2} = \frac{5}{4} \times \frac{1}{2}=\frac{5}{8}$

So, Ethan can read 1 page in 5/8 of a minute.
