X i. A family spends 1/10 of its annual income for housing 1/4 for food and clothing, ils for general expenses, and /15 for entertainment. What fractional part of their income is spent on these items altogether?
The answers A, find a number which all the denominators multiply into then times the numerator however many times the original denominator divides into it. For example if you had 2/3 and 2/4 then the lowest number that both 3 and 4 divide into is 12. So to get the numerator divide 12 by 2 and 4. Now times the original numerator by the number it that you got from the denominator dividing into 12. This gives you 8/12 and 6/12. Add these together and it gives you 14/12
