So we're given five word problems that have to do with fractional values, and we're asked to solve each of the five problems.
00:06
So the first one says how many fifths are there in one half? so we're taking one half and trying to divide it into groups of one fifth, and we want to know how many groups that's going to make.
00:14
So we're dividing, which to divide fractions, we can multiply by the reciprocal, which is going to give me five over two, which is two.
00:23
So there are two and one -half fifths in one -half.
00:27
The second problem says that we have 24 kilograms of rice and we're fitting them into small plastic bags.
00:34
And each bag has three quarters of a kilogram.
00:37
How many bags will we need? so we're taking 24 and dividing it into groups of three -fourths.
00:42
So how many groups are we going to make? 24 times four thirds.
00:47
And i can do some cross -simplification here.
00:50
So eight times four is going to give me 32 bags.
00:54
So we would have 32 bags of three -fourths rice.
00:57
That would give me a total of 24 kilograms.
01:03
The next question has six and two thirds pails of water, and they're being poured into three equal containers.
01:09
How many pails are going to be in each container? so we're taking six and two thirds and dividing it into groups, three pails evenly.
01:17
So i'm going to convert six and two thirds into an improper fraction.
01:20
So it's 20 thirds divided by three over one.
01:25
And so i'm going to do 23rd.
01:30
Times 1 over 3.
01:33
So that's 20 9ths...
