simplify​

Answer 1

Answer:

15

Explanation:

Given that,

$1\frac {3}{4}$ × $2\frac{2}{5}$ × $3\frac{4}{7}$

Changing mixed fraction to improper fraction

⇒(4×1 + 3)/4 × (5×2 + 2)/5 × (7×3 + 4)/7

⇒(4+3)/4 × (10+2)/5 × (21+4)/7

⇒7/4 × 12/5 × 25/7

⇒(7×12×25)/(4×5×7)

⇒(84×25)/(20×7)

⇒2100/140       (∵Cancel in '7' table)

⇒300/20          (∵Cancelling '0')

⇒30/2      

⇒15

∴answer is 15.
