Answer 1

1) -24

2) -11

3) -15

4) -2.25

5) 17.2

6) -69.68

7) 6/5

8) 5/2

9) -5/8

Step-by-step explanation:

We need to find answers to each number.

Some rules to be followed while solving integers.

Since all questions are of addition and subtraction we follow following rules.

• If both values have same sign(+,+ or -,-) , then add the values and take sign of the values
• If both values have different sign(+,- or -,+) then subtract the values and take sign of the larger value.

$1. -16+(-8)\\= -16-8\\= -24$

$2. (-4)-7\\= -4-7\\= -11$

$3. -24-(-9)\\= -24+9\\= -15$

$4. 6.25+(-8.50)\\= 6.25-8.50\\= -2.25$

$5. 10.8-(-6.4)\\= 10.8+6.4\\= 17.2$

$6. -54.26+(-15.42)\\= -54.26-15.42\\= -69.68$

$7. -1\frac{1}{2} + 2\frac{7}{10}\\= \frac{-3}{2} + \frac{27}{10}\\Taking\,\,LCM\,\,of\,\,denominator\\=\frac{-3*5+27}{10}\\=\frac{-15+27}{10}\\=\frac{12}{10}\\=\frac{6}{5}$

$8. \frac{5}{8}-(-1\frac{7}{8})\\= \frac{5}{8}-(\frac{-15}{8})\\=\frac{5}{8}+\frac{15}{8}\\Taking\,\,LCM\,\,of\,\,denominator\\=\frac{5+15}{8}\\=\frac{20}{8}\\=\frac{5}{2}$

$9: \frac{1}{4}-\frac{7}{8}\\Taking\,\,LCM\,\,of\,\,denominator\\=\frac{1*2-7}{8}\\=\frac{2-7}{8}\\=\frac{-5}{8}$
