ou need 1 1/4 cups of sugar to make 20 cookies. How many cups of sugar will you need to make 16 cookies? cups of sugar
frutty [35]

Answer:

To make 16 cookies you will need 1 cup of sugar.

Step-by-step explanation:

Given:

Sugar needed to make 20 cookies =  1 1/4 cups

To Find:

Sugar needed to make 16 cookies = ?

Solution:

For making 20 cookies 1 1/4 cups of sugar is used

So to make 1 cookie  we need

=>\frac{1\frac{1}{4}}{20}

=>\frac{\frac{5}{4}}{20}

=>\frac{5}{4} \times \frac{1}{20}

=>\frac{5}{80}

=>\frac{1}{16} cups of sugar

Now to make 16 cookies  we need,

=>16 \times \text{sugar needed to make one cookie}

=>16 \times\frac{1}{16}

=>\frac{16}{16}

=> 1

There are a total of 84 students in a robotics club in the science club. The science club is 12 more students in the robotics cl
Anna [14]

Answer:


Step-by-step explanation:

Let the Number of students in the Robotics club be x

So , the number of students in the Science club must be x+12

(Because it is given that the science club have 12 more students.)

Total number of students = 84

So ,

x+(x+12)=84

combining the like terms we get

2x+12=84

Subtract 12 from both sides

2x=72

Divide both sides by 2

x=36

So ,


Number of students in the Robotics club = 36

Number of students in the Science club =36+12 = 48
