1 loaf = 1 tb butter
This is a multiplication problem
[tb of butter to make a loaf] x [number of loaves]
= 1 x 4
= 4
1 multiplied by any number is that other number.
quick tip: breaking up problems by sentence usually helps to make word problems easier to digest. look for numbers and their associations, and then look at how the word problem describes each object's relationship.
