Okay, so how to do it, so the parentheses around the two doesn’t matter, you can times 4.16 and .2 together to get .832, it is fairly easily. How I got it: 4.16 is on the top of .2, the decimals line up, you add a zero behind the 2 to make it a 20, now you just Times 4.16 by .20 to get .832
Rob saved $30. Do you have to explain, if so since he saved $6 for every $15, you would do 75 divided by 15 which is 5 then you would do 5 times 6 which gives you 30.
