To prepare for the fun picnic, Bob's recipe needs 1/6 cup of sugar and 1/3 cup of flour. How many cups in all does Bob need for the recipe?
+61 1/2 cup of both flour and sugar.
in order to add fractions one must first find the least common denominator(LCD) (in this case both 3 and 6 go into 6 so the LCD is 3)
1/3 * 2/2= 2/6 we multiply by 2/2 because the fraction=1 thus the value of the fraction remains the same
1/6 *1/1=1/6
2/6+1/6=3/6 we then simplify 3/6 into 1/2
so 1/2 cups in total
