The denominator must be the same, so just think of the LEAST COMMON MULTIPLE, The LCM here is 8, because you can multiply 4 by 2 to get 8.
so when you multiply, you multiply both on the top and on the bottom, so this would be:
3 x 2 / 4 x 2 = 6 / 8
Now you can add or subtract: 6/8 - 1/8 = 5/8
Answer:
See explanation below
Step-by-step explanation:
Given the ratio between two groups to be 3:7
Total ratio = 3+7 = 10
Total sweet shared = 30sweets
For the group with ratio of 3;
Share = 3/10×30
Share = 3×3
Share = 9 sweet
For the group with ratio of 5
This share = 7/10×30
This share = 7×3
This share = 21sweet
70 x 100 = 7,000
Therefore, 70 hundred is equal to 7 thousands.
