Question

so my math teacher made us do a review and I forgot how to do 8.90 x 15 bc when I do it's not in the multiple choices help​

Answer 1

133.5

An easy way of doing this is to ignore the decimal so consider it as 89 instead because 0 is insignificant. So do 89x15 = 1335 we know that 8.90 has 1 decimal place because 0 is not significant so you just add 1 decimal place which becomes 133.5
