Let the two numbers be represented by x and y.
.. y = 29 +3x
.. 5(y -x) = 345
From the second equation,
.. y -x = 345/5 = 69
Substituting for y in the first, we have
.. 69 +x = 29 +3x
.. 40 = 2x
.. x = 20
Then
.. y = 29 +3*20 = 89

The two numbers are 89 and 20.

X = 29 + 3y
5 (x-y) = 345
5x-5y = 345
5 (29+3y) -5y = 345
145 +15y-5y = 345
10y +145-145 = 345-145
10y = 200
y = 20
x = 29 + 3y = 29 + 3(20) = 29 + 60 = 89

If you are having trouble with ratios you can look at them as fractions. The first number being the numerator and the second number being the denominator or the other way around. When you are asked to find an equivalent ratio, you just have to find an equivalent fraction.

If I buy 3 4/5kg of cherries and 2 1/4 of strawberry's what is the Mass kilograms of fruit
lisov135 [29]
If you would like to know how many kilograms of fruit do you have, you can calculate this using the following steps:

3 4/5 kg of cherries + 2 1/4 kg of strawberries = 3 4/5 + 2 1/4 = 19/5 + 9/4 = 76/20 + 45/20 = (76 + 45) / 20 = 121/20 = 6 1/20 kg of fruit

The correct result would be 6 1/20 kilograms of fruit.
