100 = 10^2
so 10^9 * 10^2 = 10^11 kilometers in 100 years
14/15 - 5/12
Common denominator is 60.
56/60 - 25/60
= 31/60 as fraction.
= 0.516 as decimal.
Answer:
x/16 + 10
Step-by-step explanation:
10+(x÷16)
To add or subtract expressions, expand them to make their denominators the same. Multiply 10 times 16/16.
10 x 16 / 16 + x/16
Since 10 x 16 / 16 and x/16 have the same denominator, add them by adding their numerators.
10 x 16 + x / 16
Do the multiplications in 10×16+x.
160 + x / 16 = x/16 + 10
Answer:
Step-by-step explanation:
Sammi has 2 1/3 feet of rope.
To write this type of fraction = 2 + 1/3 - The integer 2 in the expression is the amount of feet of rope that was cut.
Thus to know the number of 1/2 foot pieces produced, let this number be x. Thus, we have 1/2 of x pieces = 2
x/2 = 2; x = 2x2 = 4.
Thus, Sanmi has 4 pieces of 1/2 foot long piece each of rope.
