B) 6/5 ∶ 24/50 − 3/2 =

Answer 1

Explicación paso a paso:

A)

( 40×11×7 / 28×2×10 ) –1/4 + 5/12

( 3080 / 560 ) –1/4 + 5/12

( 11/2 ) – 1/4 + 5/12 =

11×4–2×1/2×4 = 44‐2/8 = 42 / 8 = 21/4

21/4 + 5/12 = 21×12+4×5/4×12 =

252 + 20 / 48 = 272 / 48 = 17/3

A) = 17/3

B )

6/5 ÷ 12/25 –3/2 =

6×25 / 5×12 – 3/2 =

150 / 60 = 15/6

15/6 – 3/2 = 15×2–6×3/6×2 =

30 – 18 / 12 = 12 / 12 = 1

B ) = 1
