First, we compute the highest common factor between the numbers of toys. The highest common factor for 45, 105 and 75 is 15. Therefore, we will need 15 shelves. On each shelf, there will be 45/15 = 3 dolls, 105/15 = 7 footballs and 75/15 = 5 small cars
Step 1: plug in the numbers. 7(6)-4
Step 2 multiply 7x6 42-4
Measure the perimeter and the are and the see how long and wide the tile is
23(x)-85
Substitute 12 for x
23(12)-85
276-85
