Question

paki sagot nman po yung may solution po . salamat​

Answer 1

1. 9/5

2. 31/15

3. 5/4

Step-by-step explanation:

$1. \: \: \: \frac{ - 7}{10} + \frac{5}{2} = \frac{ - 7 \times 1 + 5 \times 5}{10} \\ = \frac{ - 7 + 25}{10} = \frac{18}{10} = \frac{9}{5} \\ \\ 2. \: \: \: \frac{5}{3} - ( \frac{- 2}{5} ) = \frac{5}{3} + \frac{2}{5} \\ = \frac{5 \times 5 + 2 \times 3}{15} = \frac{25 + 6}{15} = \frac{31}{6} \\ \\3.\: \: \:\frac{1}{2}+\frac{3}{4} \: = \: \frac{2+3}{4} \: = \: \frac{5}{4} cup \: of \: sugar$

Answer 2

$3) \: \frac{3}{4} + \frac{1}{2}$

$= \frac{3}{4} + \frac{3}{4} = \frac{5}{4} cups$
