Question

2.34 * 15.7 = (long multiplication)

Answer 1

`2.34 * 15.7=36.738`

Explanation:

We are given two numbers 2.34 and 15.7 , we have to multiply both the terms that is
`2.34 * 15.7` using long multiplication method,

First remove decimals, we get,

`(234)/(100) * (157)/(10)`

We first multiple numerators,
`234 * 157`

Multiply the top number by the bottom number one digit at a time staring from the ones digit from right to left.

234 on multiplication with 7 gives 1638

carry over the term to the next term like 7 × 4 = 28 so carry 4 over 3.

write 0 at the end of 2nd row, and then Multiply 234 with 5 gives 11700

now write 0 0 at the end of 3 rd row and Multiply 234 with 1 gives 23400

Now add all the three rows, we get,

1638 + 11700 + 23400 = 36738

Thus,
`(234)/(100) * (157)/(10)=(36738)/(1000)=36.738`

So,
`2.34 * 15.7=36.738`
