How to simplify this math problem? 120 divided by 2.4 divided by 2 - 1.35 + 11631 x 0.02?

Question

Show me different steps on how to do this math problem. How can I learn an easy way to do these type of math problem.

Answer 1

use your calculator

or 120/2.4/(2-1.35+11631*0.02) = 120/2.4/233.27 = 120*233.27/2.4 =
11663.5

Answer 2

Remember your order of operations.

120 divided by 2.4 divided by 2 - 1.35 + 11631 x 0.02

translates to this:

(120/2.4)/2 - 1.35 + (11631 x 0.02)

Do the stuff in the parentheses first, then division and/or multiplication, and then addition and/or subtraction from left to right.

(120/2.4)/2 - 1.35 + (11631 x 0.02)
= (50)/2 - 1.35 + (232.62)
= 25 - 1.35 + 232.62
= 23.65 + 232.62
= 256.27


In your original problem, you have no parentheses, so it's really a strict left-to-right solution. I added parentheses for readability and to show which part of that initial division sequence I'd attack first, and also to empasize doing the multiplication *before* the subtraction and addition. If your original problem had any parentheses, then that could change the solution I gave.

Answer 3

You need to write the problem more clearly first, so we know which operations to do first. Some parentheses would help! (Is 2.4 divided by the 2 only? or is it divided by 2 - 1.35? or 2 - 1.35 + 11631? .... you see what I mean?)

Easy way to do these = Pay attention when someone shows you how to do them, to make sure you understand. Then do a bunch of them! Practice makes perfect!!!

Answer 4

truly undemanding - operations are so as multiplying and dividing are first then including and substracting so which you suggested the priority is this a hundred and twenty / 2.4 / 2 - a million.35 + 11.631 X 0.02 so we get doing the 1st 50 / 2 - a million.35 + 11.631 x 0.02 then 25 - a million.35 + 11.631 x 0.02 to get 25 - a million.35 + 0.23262 so the respond is 23.88262
