Question

Plz find the value of 160/ 2×7 + 160/12×7 + 160/ 12×17 + 160/22×17 + 160/22×27 + 160/32×27

Answer 1

160/14(1+1/6)+160/34(1/6+1/11)+160/54(1/11+1/16)

= 160*7/(14*6) + 160/34(17/11*6)+160/54(27/11*16)
= 40/(3) + 40/(11*3) + 40/(8*11)
= 40/3(1+1/11) + 40/(8*11)
= 40/3(12/11) + 40/(8*11)
= 40/11 ( 4 + 1/8)
= 40/11 (33/8)
= 5*3 = 15

Answer 2

Answer:

15

Step-by-step explanation:

160/14(1+1/6)+160/34(1/6+1/11)+160/54(1/11+1/16)

= 160*7/(14*6) + 160/34(17/11*6)+160/54(27/11*16)

= 40/(3) + 40/(11*3) + 40/(8*11)

= 40/3(1+1/11) + 40/(8*11)

= 40/3(12/11) + 40/(8*11)

= 40/11 ( 4 + 1/8)

= 40/11 (33/8)

= 5*3 = 15
