Question

Simplify using the following properties:- A. 1/4 ÷ 4 × (-1/20) B. 3/20 +4/48 -7/16 + -3/24 C. (1/3 + 2/5) × (3 -1/2) 4. (3/8 - 7/11) × (-4/7 × 7/16)

Answer 1

Answer = A. -1/320

B. -474/1440

C. 11/6

D. -23/352

A. 1/4÷4×(-1/20)

1/4÷4/1*(-1/20)

1/4*1/4*(-1/20)

1/16 × -1/20

-1/320

B. 3/20+4/48-7/16+(-3/24)

3/20+4/48-7/16-3/24

(3×72)+(4×30)-(7×90)-(3×60)/1440

216+120-630-180/1440

336-810/1440

-474/1440

C. (1/3+2/5)*(3-1/2)

(1*5+2*3)/15*(3*2-1)/2

(5+6)/15*(6-1)/2

11/15*5/2

11*1/3*2

11/6

D. (3/8-7/11)*(-4/7*7/16)

(3*11-7*8)/88*(-1/4)

(33-56)/88*(-1/4)

-23/88*-1/4

-23/352
