This problem says chelsea is sewing handmade scarves for her sisters and friends.
00:04
She has four and five, six yards of materials and needs seven -eighths of a yard of material for each scarf.
00:10
How many scarves can she make with the existing material? and to figure this out, what we need to do is take the total amount of material we have, the four and five, six yards, and divide it by the number of yards that it takes for each scarf, the seven -eighths.
00:25
And to be able to divide here, we need to take the first fraction out from mixed number form and get it to improper.
00:30
Fraction form, which we can do by taking the denominator, multiplying by the whole number, which in this case is 6 times 4, 24, and then adding it to the numerator that's already existing, which is 5, so that would be 24 plus 5.
00:43
To give us 29 still over 6, and that's divided by 7 .8s, and when we divide fractions, we multiply by the reciprocal.
00:51
So we'll change this to multiplication, and we'll change 7 .8s to be 8 over 7...
