4 - 3/8 = 3 8/8 - 3/8 = 3 5/8
1 4/9 (I think I had to do this in my head & I usually work it out on paper.)
Not entirely sure, but wouldn't it be 1/8?
To work this out you need to amend the fraction to one that can be halved.Three quarters is the same as six eighths, now you can work out the answer.Three eighths is half of three quarters.
It's the greatest length you could cover if somebody cut up one inch into eight equal pieces and gave you three of them to work with.
It will help a lot if you know how to write "four tenths" in numbers.Four tenths = 0.47.3 minus 0.4 = 6.9
Three out of four
If you mean: 4 times 80/5 and 7 times 80/8 then no because they work out as 64 and 70 respectively
That is impossible, it doesn't work. the answer in the textbook or whatever must be wrong. It is 5
-3 + ? = 5 add 3 to both sides ? = 8
1 = 4/4 - 3/4 = 1/4
You turn the denominator into the same value so four times three would be twelve so you multiplied the three by four so you times the one by four and then you multiplied the four by three so you would times the three by three so the answer would be 13 over twelve
Was it installed in a three way or four way system?
