"ratio of wooden bats to metal bats is 2 to 1" basically means "there are twice as many wooden bats (compared to metal ones)". so if we had 3 metal bats, then we'd have 2*3 = 6 wooden bats. if we had 7 metal bats, then we have 14 wooden ones (because 2*7 = 14). and so on. the basic rule is to multiply the amount of metal bats by 2 to get the amount of wooden ones.
we can go in reverse to divide the amount of wooden bats to get the amount of metal ones. so 20/2 = 10 is the amount of metal bats.
a more formal approach is to use the proportion below to solve for x
20/x = 2/1
20*1 = x*2
20 = 2x
2x = 20
2x/2 = 20/2
x = 10
and we get the same answer.
28 shorts, and 279 t-shirts.
dots is selling t-shirts for $2 a piece and has sold 279 of them that is $558.
279 shirts x 2 (dollars)= $558.
we need to see how many shorts were sold, so we are going to take the money we know didn't come from shorts and subtract it from their total sales.
$112 is left, divide 112 by 4 to see how many shorts were sold.
112/4= 28 shorts.
28 shorts and 279 t-shirts.
step-by-step explanation: 21/7=3, so there is no change.
