Answer 2

a.350

b.240

c.210

d.270

Explanation:

We have to find the product of given number using place value.

a.
`5* 70`

Place of 7 in 70 =tens

`5* 7\; tens =35 \;tens`

`5* 70=35* 10=350`

c.
`7* 30`

Place of 3 in 30 =Tens

`7* 3 \;tens=21 \;tens`

`7* 30=21* 10=210`

b.
`60* 4`

Place of 6 in 60=Tens

`6 \;tens* 4=24 \;tens`

`60* 4=24* 10=240`

d.
`90* 3`

`9\;tens* 3=27\;tens`

`90* 3=27* 10=270`
