Step-by-step explanation:

A school has 7 buses. Each bus has 40 seat

1 bus = 40 seat

To find the number of seats on 7 buses we multiply the number seat of each bus with total number of buses

7 buses = 40 * 7 = 280

40 can be written as 4 tens

7*40=7 group of 4 ten

7 groups oftens= tens

7 group of 4 tens

we add 7 groups of 4 tens , 4 +4+4+4+4+4+4 = 28 tens

7 groups of___4___tens= 28tens
