We have to find the product of given number using place value.
a.[tex]5\times 70[/tex]
Place of 7 in 70 =tens
[tex]5\times 7\; tens =35 \;tens[/tex]
[tex]5\times 70=35\times 10=350[/tex]
c.[tex]7\times 30[/tex]
Place of 3 in 30 =Tens
[tex]7\times 3 \;tens=21 \;tens[/tex]
[tex]7\times 30=21\times 10=210[/tex]
b.[tex]60\times 4[/tex]
Place of 6 in 60=Tens
[tex]6 \;tens\times 4=24 \;tens[/tex]
[tex]60\times 4=24\times 10=240[/tex]
d.[tex]90\times 3[/tex]
[tex]9\;tens\times 3=27\;tens[/tex]
[tex]90\times 3=27\times 10=270[/tex]
