Me with these : 3 i would really appreciate it.

For the first one he has 3100 that comes out of his monthly payment so look for the one that has 3100 or more on his paycheck and that will be the month that he has enough to pay his monthly expencize. I hope that is right im pretty sure it is.

I wish I could help you with the second one but the way I would explain it is to confusing but I hope you find help on that one! have a good day

Given that we Jenny wants to equivalent fraction of 45% then convert into reduced fraction and then convert into decimal equivalent.

She has already shown her work. We just need to find the error if any.

to convert any percent value we just divide that number by 100 because percent itself means divide by 100.

Hence first step 45%=45/100 is correct.

Then she needed to convert into reduced fraction. To do that she divided numerator and denominator both by 5 and got 9/20.

step 2 is also correct.

Now she needs to convert into decimal equivalent so she divided 9 by 20 and got 4.5 while the correct answer should be 0.45

Hence she did error when converting fraction form into decimal form.
