Avery has 2 blue marbles. One sixth of Avery's marble are blue. How many marbles does Avery have?
katrin [286]

Answer:

Step-by-step explanation:

The equation

2 = (1/6)x represents this situation.

2 is 1/6 of some value.  In this case, the value is the total number of marbles.  2 represents 1/6 of the total number of marbles is how to read that equation in context.  Solve that equation for x

2 = (1/6)x  

12 = x           (multiply both sides by 6 to get rid of the fraction)

What’s the calculation of the equation 5/8-1/4=
Kay [80]

Answer: 3/8

Explanation: To subtract unlike fractions such as 5/8 - 1/4, first find a common denominator. The common denominator of 8 and 4 will be the least common multiple of 8 and 4 which is 8.

Notice that our first fraction already has 8 in the denominator so it stays the same. To get 8 in the denominator of 1/4, we multiply the numerator and denominator by 2 to get 2/8.

Now we have 5/8 - 2/8.

To subtract like fractions, we simply subtract the numerators to get 3 and keep our denominator of 8 and we have 3/8.

Since 3/8 is in lowest terms, it's our final answer.

Therefore, 5/8 - 1/4 = 3/8.
