many rides can she take?
Answer:
She can take 21 rides
Step-by-step explanation:
The best way to solve this problem is to have a number that isn't a decimal. Since she can't take half a ride, and the rides cost one dollar each, subtract 50 cents from 21.50. You'll end up with 21. Divide 21 by 1, and the quotient is 21 rides.
1 13/20 pounds are left.
Subtraction is the process of taking away a number from another. It is a primary arithmetic operation that is denoted by a subtraction symbol (-) and is the method of calculating the difference between two numbers.
here, we have,
Caitlin has 4 3/4 pounds of clay .
She uses 1 1/10 pounds to make a cup
,and another 2 pounds to make a jar
i.e. she has = 4 3/4-(1 1/10+2)
=19/4 -31/10
=66/40
Hence, 1 13/20 pounds are left.

Bertie needs 12 1/4 cups of flour to make 3 1/2 pans of biscuits.
The basic idea of multiplication is repeated addition. But as well as multiplying by whole numbers, we can also multiply by fractions, decimals and more.
Given that, Bertie needs 2 1/3 cups of flour for each pan of biscuits she bakes. She wants to bake 3 1/2 pans of biscuits.
Since, 1 pan needs 2 1/3 cup of flour.
So, for 3 1/2 pans = 3 1/2 × 2 1/3
= 7/2 × 7/2
= 49/4
= 12 1/4
Hence Bertie needs 12 1/4 cups of flour to make 3 1/2 pans of biscuits.
