For an experiment, a scientist needs 1/2 cup baking soda for 4/5 liter of water. Using this ratio, how much baking soda is needed for one liter of water? Answer choices-

4/10 cup

5/8 cup

8/5 cups

10/4 cups

5/8 cup of baking powder.

Step-by-step explanation:

Hence, using the ration given in the above question:

4/5 liter of water = 1/2 cup of baking soda

1 liter of water = x cup of baking powder

Cross Multiply

4/5 liter of water × x cup of baking powder = 1 liter of water × 1/2cup of baking powder

x cup of baking powder = 1 liter of water × 1/2cup of baking powder/4/5 liter of water

x cup of baking powder = 1/2 ÷ 4/5

x cup of baking powder = 1/2 × 5/4

x cup of baking powder = 5/8 cup of baking powder.

Therefore,

5/8 cup of baking soda is needed for one liter of water.
