900 - without using a calculator !
15 times 60=900
60 ÷ 4 = 15
4 times 15 = 60 so the answer is negative 60.
10 times 6 = 60 or 12 times 5 = 60 pr 15 times 4 = 60 or 20 times 3 = 60 or 30 times 2 = 60
60 multiplied by 15 is 900.
900 divided by 60 is 15. So, 60 goes into 900 15 times.
exactly 4 times. 15 x 4 = 60
15 X 4 _____ 60
60/15 = 4.
Since 60 can be factored to 4 times 15, then radical 60 equals 2 times radical 15.
This is a no brainer ... 60! 15+15+15+15= 60
15
