How do you reduce 42/70- math

Answers

Answer 1

Answer: Well i think you mean to simplify 42/70 which is:

(2 * 3 * 7) / (2 * 5 * 7)
= ((2 * 3 * 7) : (2 * 7)) / ((2 * 5 * 7) : (2 * 7))
= (42 : 14) / (70 : 14) = 3 / 5

1/4 x 16

Max delivers 8,520 pieces of mail in one year. If he delivers the same number of pieces of mail each month, about how many pieces of mail does he deliver in 2 months? Explain your steps.Can you help me and explain this question... Thanks!

Answers

So there are 12 months in a year and he delivers 8,520 in that time. You must divide 8,520 by 12 which gives you how many he delivers in one month. 8,520/12=710. You are looking for two months so you should then multiply 710 by two giving you how much he delivers in 2 months.
710*2=1,420
Max delivers 1,420 pieces of mail in two months

Bella pays 7 payments of $5 each to a game store. She returns none game and receives $20 back. What is the change to the amount of money she has.

Answers

Answer:

Bella has $15 less

Step-by-step explanation:

Bella made 7 payments of $5 each. So, total payment made by her was $7*$5 = $35$ . As such, Bella had $35 initially. She played all games and received $20 back. This means that she lost $ 15 that is $35 - $20 = $15, in the game.

Therefore, she now has $15 less than the amount of $35 that she had initially. So, $15 is the the change to the amount she has now.

15$7 payments of 5$ = 35$ if she only gets 20$ back she lost 15$
