Xavier and his little sister are saving up money to buy a joint birthday present for their mother. Xavier already has $13 saved and plans to save $11 per week from his allowance.
His sister has $22 saved so far and will save $10 per week from hers. The two siblings will
soon have saved the same amount towards their mother's gift. How long will that take? How
much will each one have saved?

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
