18 x 35 = 630 630 / 30 = 21 So the answer is 21.

30. Here's how:21 times 10 = 210210 divided by 7 = 30Check:30 times 0.7 = 21
30/21 = 1 with a remainder of 9

Yes, because 3 is the only number that both can be divided by to further reduce both sides. 21/3 = 7, 30/3= 10 so, 21/30 = 7/10
K divided by 21 divided by N is equivalent to divided by?
First we set out the problem: 7/10 divided by 1 1/6 Since 1 and 1 over 6 is a mixed fraction we have to convert it into a improper fraction which is 7/6 (6x1=6+1=7) Now our problem looks like this: 7/10 divided by 7/6 We look at the denominators and think "what number can they both fit into?" They can both fit into 30 (10x3=30 and 6x5=30) What we do to the bottom, we must do to the top. so 7x3= 21 so: 21/30 Now 7x5=35 so 35/30 Now it looks like this: 21/30 divided by 35/30 Since this is a division problem, we have to FLIP the second fraction, and as we are flipping, we are turning this into a multiplication problem: 21/30 divided by 30/35. Now to make this easier, we can CROSS CANCEL. Now 30 goes into 30 once so we can cross both of them out and leave a 1. 21/1 MULTIPLIED by 35/1 = 21 x 35 which equals 735. I know this all looks complicated but it really isn't. Keep practising and you'll get there! Note: I'm 8
