Please Help me to Solve it.​

Answer 1

$(i) (–5) × 4 \: \: and \: \: –5 + 4 \\= \: –20 \: \: and \: \: –1 \\ \\\bold{ \frac{ - 20}{ - 1} }\\ \\\\ \\(ii) 64 ÷ 4 \: \: and \: \: 32 - 18 \\= 16 \: and \:14 \\= 8 \: and \: 7 \\ \bold{ \frac{8}{7} }$

Answer 2

Step-by-step explanation:

(i) numerator = -5 × 4

denominator = -5 + 4

Hence numerator = -20

denominator = -1

rational number = -20/-1

(ii) numerator = 64÷4

denominator = 32-18

Hence Numerator = 16

Denominator = 14

rational number = 16/14

= 8/7
