If 7/12 is multiplied by a fraction less than 1 what would be the product

olga55 [171]

Answer:

<em>Examples below</em>

Step-by-step explanation:

We have the fraction

$\frac{7}{12}$

It's required to multiply it by any fraction less than 1. Let's select the following fractions. All of them are less than 1 because the numerator is less than the denominator:

$\frac{1}{7}$

$\frac{4}{5}$

$\frac{6}{35}$

The required products are:

$\frac{7}{12}\cdot \frac{1}{7}=\frac{7}{7*12}=\frac{1}{12}$

$\frac{7}{12}\cdot \frac{4}{5}=\frac{4*7}{12*5}=\frac{7}{15}$

$\frac{7}{12}\cdot \frac{6}{35}=\frac{6*7}{12*35}=\frac{1}{10}$

Two trains leave a city at 3 P.M. One train goes east at a constant rate of 70 mph. The other goes west at a rate of 62 mph. How

andrey2020 [161]

Answer:

4 hours

Step-by-step explanation:

The general formula for distance, rate and time is:

d = rt, where distance is the product of rate multiplied by time

Given that one train is moving at a rate of 70 mph and one is moving at a rate of 62 mph in the opposite direction, the combined distance over time is equal to 528 miles. Using the variable 't' for time:

70t + 62t = 528

Combine like terms: 132t = 528

Divide both sides by 132: 132t/132 = 528/132 or t = 4 hours
