Bob is building a scale model of his bike. He wants his model to be 1/6 as long as his bike. If Bob's bike is 66 inches long, How long will his model be?

11 inches

Step-by-step explanation:

To work this out you would first need divide 66 by 6, Which is 11. Then you would multiply this by 1. This is because in this example you are working out what 1 sixth of 66 is, then after you would multiply by the numerator to work out how much of the whole amount.

The formula to work out fractions of an amount you would divide the amount by the denominator and then multiply it by the numerator.

1) Divide 66 by 6.

2) Multiply 11 by 1.

3) His bike would be 11 inches long

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
