What is the GFC of 40 and 60

Svetradugi [14.3K]

Answer:

GCF: 20

Step-by-step explanation:

The thing you want to do is factor both numbers down to their lowest primes.

40:2 * 2 * 2 * 5

60:2 * 2 * 5 * 3

Now underline what is in both sets of primes. I'll bold them. The number that is bolded comes from 2 * 2 * 5 which is 20

The highest common factor is 20

marin [14]

Answer:

25.2 minutes

Step-by-step explanation:

step 1

Find the area of the given wall

$A=(7)(6)=42\ ft^2$

step 2

we know that

You can paint 75 square feet of a surface every 45 minutes

using proportion

Find out how long it takes you to paint a surface area of 42 square feet

$\frac{75}{45}\ \frac{ft^2}{min}=\frac{42}{x}\ \frac{ft^2}{min}\\\\x=45(42)/75\\\\x=25.2\ min$

Write a fraction that is equivalent to 7/10 = _ /_

labwork [276]

A fraction that is equivalent to $\frac{a}{b}$ will have the form $\frac{a\times A}{b\times B}$ , where A and B are equivalent and factors that are multiplied in.
The product fraction should be easily simplified using A and B to get the original fraction.

<em>In the case of your fraction </em> $\frac{7}{10}$ you will need to find a fraction which is a product of this: $\frac{7\timesA}{10\timesB},A=B$
