Please post your answers with explanations

Re: . by Basildvalour(m): 1:27pm On Jul 12, 2016

~ 3.3 or 23/7 = 3 2/7

90/1 ÷ [3(4+6)] + 8/1÷ 4(5+2)

90/1÷ [3(10)] + 8/1÷ 4(7)

90/1÷30/1 + 8/1÷28/1

90/1*1/30 + 8/1*1/28

90/30 + 8/28

3/1 + 2/7

3+0.285
~3.3 Ans.

USING LCM
3/1+2/7

21+2/7
= 23/7
=3 2/7

Where is my BODMAS Calculator?
Op I think you too will understand what I mean in the statement above.

Re: . by byteHead(m): 1:42pm On Jul 12, 2016

Using BODMAS , solve d brackets first.... u will get

90 ÷ 30 + 8 ÷ 28
Using BODMAS again, solve division first...u will.get

3 + 2/7 = 3 2/7

Why are you dividing 90 and 8 by 1 huh

Why are you dividing 90 and 8 by 1?

That's another way of representing it so you don't get confused while trying to divide. It changes nothing and behind every whole number, there is a 1.

the number "1" also means 1/1.

2/1 is the same thing as 2.
