Question 10 Express 40 as a product of prime factors

Step2247 [10]

Answer:

2 x 2 x 2 x 5

Step-by-step explanation:

The first few prime numbers: {2, 3, 5, 7, 11, 13, 17, 19}

One way to start is to divide by the first prime until you can't do that any more, then try the next prime and so on until all the numbers in your list are prime.

40 = 2(20) divide 20 by 2 again

40 = 2(2)(10) divide 10 by 2 again

40 = 2(2)(2)(5) stop--all factors are prime.

What percent of 72 is 48 with step by step process

Sedaia [141]

Answer:

67%

Step-by-step explanation:

There are a few methods to finding the percent of a number. You can use proportions:

$\frac{percent}{100}=\frac{48}{72}$

The 'percent' is the percent of the fraction that you are looking for, or 48/72.

Cross-multiply: 72x = (48)(100) or 72x = 4800

Divide both sides by 72: 72x/72 = 4800/72

Solve for 'x': x = 66.6666...

Round 66.666.... to the nearest percent: 67%
