To solve this problem you must apply the proccedure shown below:
1. You have the following ratio given in the problem above:
11:1
2. You can rewrite that ratio as below:
11/1=11
3. Then, to find three equivalent ratios, you only need to multiply the numerator (11) and the denominator (11) by the sam number. Therefore, you have:
11x2/1x2=22/2=11
11x3/1x3=33/3=11
11x4/1x4=44/4=11
Therefore, as you can see, the answer is:
22:2
33:3
44:4

Answer:
35 pounds
Step-by-step explanation:
To solve this, we can set up a proportion.
Let's name the weight of the wheat flour "x."
3/5=21/x
Cross multiply to solve.
3*x=5*21
3x=105
x=35
The weight of the wheat flour is 35 pounds.
