Answer:
24 pencils : 64 pens
Step-by-step explanation:
pencils : pens
12:32
Twice as many pencils mean multiply each by 2
12*2 : 32*2
24: 64
24 pencils : 64 pens
Using conversion of units, it is found that Dylan needs another 1.29 ounces of cheese.
----------------------------
- The conversion of units are applied using a rule of three.
- Each gram has 0.035274 ounces. How many ounces are there in 150 grams?
1 gram - 0.035274 ounces
150 grams - x ounces
Applying cross multiplication:

----------------------------
- Dylan has 4 ounces of cheddar cheese.
- He needs 5.29 ounces.
- Thus, he needs another 5.29 - 4 = 1.29 ounces.

1. y= 2/5 because 2/5 + 2/5 = 4/5
2. x = 4/8 because 4/8 - 3/8 = 1/8
3. d = 1 or 5/5 because 1 ( or 5/5 ) - 1/5 = 4/5
Tip - use inverse operation to get the answers. For example for 1 since 2/5 is a positive number I subtracted 4/5 - 2/5 and that’s how I got 2/5 for 1. :D
