On Saturday, Craig rode his bike 5/8 of a mile. On Sunday, he rode his bike 1/2 of a mile. Craig added 5/8 and 1/2 to find the total distance, in miles, he rode his bike on the two days. Craig said 5/8+1/2=6/10. Explain why Craig’s answer is not reasonable and give me the new equation and answer
When you add fractions, the denominators must be the same in order to add them together. If they change the 8 and 2 to a 8, (by finding the same multiple) Craig can then add the fractions together. the new fractions would be: 5/8 + 4/8=9/8=1 1/8

Ava has two frogs. this is 1/3 of the number of frogs Heather has. How many frogs does heather have? SHOW ME YOUR WORK
Heather has 6 frogs.
i can draw a tape diagram to show this.
I would split it into 3 boxes and label the first box with 2
I would then add each box together 2+2+2=6 or multiply 2 by 3 to get 6
