A thirty-five ounce bottle of Pedialyte contains 2,500 mg of dextrose. If a child drinks 7 ounces straight from the bottle, how many mg of dextrose will he consume?

500 mg

Step-by-step explanation:

amount of dextrose in 35 ounce Pedialyte = 2500 mg

dividing LHS and RHS by 35

amount of dextrose in 35/35 ounce Pedialyte = 2500 / 35 mg = 500/7 mg

Thus,

amount of dextrose in 1 ounce Pedialyte = 500 / 7 mg

since we have to find amount of dextrose in 7 ounce Pedialyte

we multiply LHS and RHS by 7

Thus,

amount of dextrose in 1 * 7 ounce Pedialyte = 500 / 7 * 7 mg = 500 mg

amount of dextrose in 7 ounce Pedialyte = 500 mg

Thus, As child consumed 7 ounces of Pedialyte, He consumed 500 mg of dextrose.
