6 1/2*1 1/3

i need help

Step-by-step explanation:

First let's turn the mixed numbers into improper fractions:

(You can find this by multiplying the whole number × the denominator, and then adding the product to the numerator)

Now let's multiply the fractions:

(You simply multiply numerator × numerator and denominator × denominator)

Now let's divide:

52 ÷ 6 = 8.6666666

So, we know 6 can go into 52 about eight and and half times. 8 will be the new whole number.

6 × 8 = 48

52 - 48 = 4, the new numerator.

Now we have the fraction:

Let's further simplify this:

So, in the end:

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.
