Answer:
64.21
Step-by-step explanation:
Here we are given with the a number in decimals and need to find its product with 10.
please note the rule of multiplication in decimals . When we multiply any decimal with 10, 100, 1000 , 10000 and so on.. the position of decimal in the number given to us shifts to its right by the number of places as we have the number of 0 in the multiplier
6.421 X 10
here we have only one 0 in the multiplier , hence the position of decimal in 6.421 will be shifted to one place towards right
6.421 x 10 = 64.21
