4y + 3y = 7y The answer is 7y. Because of the arithmetic rules, bracket should be taken first, then multiplication. B = bracket o = of D = division M = multiplication A = addition S = subtraction
So tis is a ratio 16 is to 3 or 16:3 if use 64 tea bags then how many cups of sugar so turn 16:3 into fraction 16:3=16/3 or 3/16, it doesn't matter then you want to find 64:x or 64/x or x/64
we know that 16/3=64/x because it tis an equivalent ratio so 16/3=64/x multiply both sdies by (3 times x) 16 times x times 3/3=64 times 3 times x/x 16 times x=64 times 3 16x=192 divide both sdies by 16 x=12 theanswer is 12 cups of sugar
