Answer:
Step-by-step explanation:
In representing mixed numbers on a number line, we need first to pay attention to the denominators. Here, denominators are 8 and 5, their least common multiple is 40, so, we will need to cut up space between two numbers on the number line on 40 pieces. Also, we have 5 and 3 wholes at these mixed numbers, so, our answer is going to be greater than 8.
We will cut the space between 8 and 9 on a number line on 40 pieces, and we will add and
and get :
So, on a number line between 8 and 9 we need to count 31 out of 40 pieces and that is the result, 8 wholes and .
Answer:
Step-by-step explanation:
We can convert these improper fractions into mixed numbers by seeing how many times the denominator goes into the numerator.
In , 9 goes into 46 5 times, with a remainder of 1. So:
.
In , 5 goes into 32 6 times with a remainder of 2, so:
.
