2/5 + 4/25 = 2x5/5x5 + 4/25 = 10/25 + 4/25 = (10 + 4)/25 = 14/25
0.84 or 0.02666... or 0.072 depending on whether it is (4/5) + (1/25) or (4/(5+1))/25 or ((4/5) + 1)/25 Another View: it would be 21 over 25.
2 plus 4/25 = 2.16
42?
If two fractions share an equal denominator, you can simply add the top, so 15 + 4 = 19, so therefore = 19/25
2/5 + 4/25 = 2x5/5x5 + 4/25 = 10/25 + 4/25 = (10 + 4)/25 = 14/25

25/20 or 1 and 1/4
5/16 + 5/4 = 25/16 or 19/16
If two fractions share an equal denominator, you can simply add the top, so 15 + 4 = 19, so therefore = 19/25
It's hard to tell what formula you mean from your description, but I think you mean 4 times 3 divided by 4 plus 10 times 5 over 12. Normally multiplication and division is performed before addition so this equals (4 * 3 / 4) + (10 * 5 / 12) 4 times 3 divided by 4 equals 12 divided by 4 equals 3 and on the other side of the plus 10 times 5 divided by 12 equals 50 divided by 12 50 doesn't go exactly into 12 but we can make it equal 25 over 6 to add the results we need to evaluate 3 plus (25 over 6) to do this, we have to use a lowest common denominator, in this case 6 3 plus (25 over 6) equals 3 * 6 over 6 plus (25 over 6) equals (18 over 6) plus (25 over 6) equals (18 + 25) over 6 43 over 6 43 over 6 is a vulgar fraction, so we extract as many whole numbers as possible 43 over 6 equals 42 over 6 plus 1 over 6 equals: 7 plus 1 over 6 7 1/6
4 over 25 as a fraction is 4 over 25 because 4 over 25 is a fraction
25 plus 4 is 29: 25 + (1 = 26, 2 = 27, 3= 28, 4 = 29)
It is, as stated, x2 - 5x + 25/4 = 0
