The least common denominator of two fraction is the least common multiple of the two denominator.
The least common multiple of 4 and 7 is their product 28, because 4 and 7 have no common factor.
Now, we need to manipulate both fractions so that they have denominator 28. Recalling that you can multiply numerator and denominator of a fraction by the same number without affecting its value, we have
So, the sum becomes
In fact, when two fractions have the same denominator, you can directly sum their numerators.

Answer:
4.
Step-by-step explanation:
Area = 1/2 * base + height
= 1/2 * 2 * 4
= 4 unit^2.
Answer: 3:8
Explanation: To get this you have to divide each number by the two numbers' GCF (Greatest Common Factor) and in this case the GCF is 10, so you divide both numbers by 10 and get 3 and 8.
Answer:
185 37 = 5 1; the scale factor is 5: 1. So every other linear measure is multiplied times 5. If we have the big right triangle and want to scale it down to make the smaller one, we write this: 37 185 = 1 5
