Answer 1

Answer:

a.350

b.240

c.210

d.270

Step-by-step explanation:

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

a.$5\times 70$

Place of 7 in 70 =tens

$5\times 7\; tens =35 \;tens$

$5\times 70=35\times 10=350$

c.$7\times 30$

Place of 3 in 30 =Tens

$7\times 3 \;tens=21 \;tens$

$7\times 30=21\times 10=210$

b.$60\times 4$

Place of 6 in 60=Tens

$6 \;tens\times 4=24 \;tens$

$60\times 4=24\times 10=240$

d.$90\times 3$

$9\;tens\times 3=27\;tens$

$90\times 3=27\times 10=270$

Answer 2

5x70=5x7tens.
60x4=6tensx4.
7x30=7x3tens.
90x3=9tensx3.
