Answer:
Step-by-step explanation:
1) Additive inverse of 7 = -7
Multiplicative inverse of 7 = 1/7
sum of Additive and Multiplicative inverse of 7 = -7+1/7 = - 48/7.
2) length of rope = 40 m.
length of one piece = 10/3.
Number of pieces = 40/10/3 = 40 * 3/10 = 12.
3) -5*x = -7
x = -7/-5 = 7/5.
4) x * (-15/20) = -5/7
x = (-5/7)/(-15/20) = (-5/7) * (- 20/15) = 100/105 = 20/21
5) Let length of cloth making one shirt = x.
16 * x = 24
=> x = 24/16 = 3/2 m = 1.5 m
