3/8+3/10
=3*5/8*5+3*4/10*4
=15/40+12/40
=(15+12)/40
=27/40
the simplest element for me to assert is a huge style of the time pretend the inequalities are not there the main situations it makes a distinction is that in case you multiply/divide the two factors by utilising a unfavorable, then you definately change the inequality. occasion: -2x + one million > 0 -2x > - one million x < one million/2 once you have something like fifty 3 -4 ? x-one million/3 ? 4 if that's much less complicated so you might break it up do it. x-one million/3 ? 4 -4 ? x-one million/3 or do exactly the comparable element of each piece of the inequality -4 ? x-one million/3 ? 4 -4 + one million/3 ? x ? 4 + one million/3 stable success
3/8 + 3/10
= (3 x 5)/(8 x 5) + (3 x 4)/(10 x 4)
= 15/40 + 12/40
= 27/40
3/8 + 3/10
= 30/80 + 24/80
= 54/80
= 27/40
multiply (3/8) by 5 and (3/10) by 4 so that the denominator is 40.
we get,
(15+12)/40
27/40
ans=27/40or 0.675
3/8 = 30/80
3/10 = 24/80
30/80 + 24/80 = 54/80 = 27/40
3/8 + 3/10
Take the LCM first
LCM of 8 & 10 is 40
Therefore 3/8 +3/10 = (15 +12)/40=27/40
[8*5=40 & 10*4=40]
The word " solve " is used for equations i.e. there should be an = sign.
You should probably say "evaluate" or "calculate" in this case.
15/40 + 12/40 = 27/40
Need to change the denominator to the same number.
3/8 = 30/80
3/10 = 24/80
24/80 + 30/80 = 54/80 = 27/40 (Answer)
