What is bigger 7/10 or 4/5

For this case we have the following fractions:

What we should do, is write the fractions so that both have the same denominator to be able to compare them.

We have then for fraction 2:

Then, comparing the fractions, we observe that the numerator of the second fraction is greater. Therefore it is fulfilled that:

And rewriting the fraction in its original form we have:

4/5 is bigger than 7/10

HL

Step-by-step explanation:

In the picture, it is shown that the legs QR and HG are congruent since they both have one tick mark, and the hypotenuses PR and HF are also congruent since they both have two tick marks. The HL property states that if a hypotenuse (the longest side) and a leg are congruent, the two triangles are congruent, which is exactly what this diagram shows.
