Find the lowest common multiple of 14 and 22.

154

Step-by-step explanation:

lcm = finding the smallest multiple that both numbers can reach

1. 14 = 2 × 7

  22 = 2 × 11

because they both have the same 2, that is two 2's in total. If they both have it, you can only take one of them. so it is:

2. 2 × 7 × 11

now we solve it. so 2 × 7 × 11 =

3. 154

55% are girls and 45% are boys : ) hope this

step-by-step explanation:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
