Jack's birthday is in 4 weeks. how many days is it until jacks birthday? describe how you ould use a number line to solve.

28 days

Step-by-step explanation:

There are 7 days in 1 week. We can find the amount in 4 weeks by multiplying the amount of 7 by 4.

7(4)=28 days

We can use a number line to solve this by making 4 groups of 7.

0                     7                       14                         21                        28

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
