Answer:

A. How much flour did she use for both cakes?

1 3/20 lb flour

B. If she started with a 5lb. Bag, How much flour does she have left?

3 17/20 lb

Step-by-step explanation:

Penny used 2/5lb. Of flour to bake a vanilla cake. She used another 3/4lb. Of flour to bake a chocolate cake

A. How much flour did she use for both cakes?

We solve the above question by adding up the pound of flour used for both cakes.

2/5lb Of flour + 3/4lb Of flour

Lowest common denominator = 20

= 8 + 15/20

= 23/20

= 1 3/20 lb flour

B. If she started with a 5lb. Bag, How much flour does she have left?

This is calculated as:

5 lb - 1 3/20 lb

= 3 17/20 lb

⤻ Before solving the given question , you should know the answer of these questions :

✺How do you find the hypotenuse , perpendicular and base when the angle ( $\theta \: , \alpha \: ,\beta$ ) is given ?

⇾ The longest side , which is the opposite side of right angle is the hypotenuse ( h ). There are two other sides , the opposite and the adjacent. The naming of these sides depends upon which angle is involved. The opposite is the side opposite the angle involved and it is called the perpendicular ( p ) . The adjacent us the side next to the angle involved ( buy not the hypotenuse ) and it is called the base ( b ).
