Question

Divide the sum of 13 by 11 and minus 12 by 15 by their product.​

Answer 1

$\huge {\red {\ddot {\smile }}} {\huge {\pink {\ddot \smile}}} {\huge {\purple {\ddot {\smile}}}} {\huge {\orange {\ddot {\smile }}}} {\huge {\blue {\ddot {\smile}}}} {\huge { \red{...hlo}}}$

Sum = -13/5 + 12/7

= (-91 + 60) / 35

= -31 / 35

PRODUCT = 13/7 × 1/2

= 13 / 14

DIVISION = -31 / 35 ÷ 13/14

= -31 / 35 × 14 / 13

= {-31 × 2} / {5 × 13}

= -62 / 65

ANSWER = -62 / 65
