For this you are adding two fractions together. You always want to make sure they are both improper or normal fractions and that they have a common denominator. To find a common denominator, you look at the denominators and look for a number (The smaller the better) that both can be multiplied by some number to get to. In this case, the common denominator is 10. To make the denominators the same you multiply by one so the value doesn't change. This is done by multiplying the numerator and denominator by the same number that results in the denominator becoming the common denominator.
2 1/2 = 5/2 × 5/5 = 25/10
2/5 × 2/2 = 4/10
When adding, the denominator remains the same and the numerators are added!
25 + 4 = 29
So the answer is 29/10 or 2 9/10 when converted back into a mixed number.
Hope this helped!
The ages of the crew, Marty and Blakeley are 32 years, 48 years and 24 years respectively.
<h3>Algebra</h3>
- Crew's age = x
- Marty's age = 1.5x
- Blakely's age = 0.75x
Total = crew's age + Marty's age + blakely's age
104 = x + 1.5x + 0.75x
104 = 3.25x
x = 104 ÷ 3.25
x = 32 years
Therefore,
Crew's age = x
= 32 years
Marty's age = 1.5x
= 1.5(32)
= 48 years
Blakely's age = 0.75x
= 0.75(32)
= 24 years
