URGENT!!!!!!!!!!!!!!!!!!!
I know how do do questions like 2.43 × 7, but when the whole number has 2 or 3 digits in how would I do this?

22.5 x 6 = 135

2.25 --------- Multiplicand
× 60 --------- Multiplier
---------------
------------------ product
first do multiplication as normal assuming there is no decimal point in either multiplicand or multiplier.
when there is zero at the end. count number of zeroes at the end.
in above case it is only 1 zero on 6 (or in 60)
keep zero in the unit place of product.
now multiply 226 × 6 in normal way
225
× 60
--------------
13500
now count number of places till the decimal point from the end bot in multiplicand and multiplier.
2.25 --------- Multiplicand -------- decimal places 2
× 60 --------- Multiplier -------- decimal places 0
so count 2 decimal places from the end in the product.
and put there decimal point after 2 zeroes.
135.00
or 135.
