Question

16/35×21/48 please help me I am not understanding how to do this sum

Answer 1

After you get 7/35 cancel it by 5 and get 1/5

Answer 2

you have to Short Denominator and numerator by Division via same number

Here given

16/35×21/48

that means

(16 × 21) / (35 × 48)

we can devide both numerator and denominator by 7

then we get,

(16 × 3) / (5 × 48)

again we can devide both numerator and denominator by 16

(1 × 3) / (5 × 3)

again we can devide both by 3

(1 × 1) / (5 × 1)

so, now finally we can write (1 / 5)

this is the simplest form of (16/35)×(21/48)
