400 reduced by 4 times my age is 116...
400 - 4x = 116
-4x = 116 - 400
-4x = - 284
x = -284/-4
x = 71 <===
Take 85 and multiply it by .09
we multiply by .09 instead of .9 because you have to imagine the percent is the decimal and you move it 2 places to the left, making it .09
85*.09= 7.65

5 packages of biscuits and 3 of pamphlets.
<span>The real thing to pay attention to is the word *smallest* and the numbers, along with the labels of what they represent. If you can only have who packages of 20, that's a limiting point. Make sure whatever multiple you buy, the biscuits have a value that ends in 0, such as the numbers 20, 30, 40, 50, 60 etc. The first number to multiply 12 by to give you a number like that is to multiply it by 5. That gives you 60. Then multiply 20 by 3 to get sixty. </span>
