Answer:
1,600
Explanation:
When dividing with fractions, remember this rule!!!!
KEEP SWITCH FLIP
- Keep the first fraction
- Switch the sign from division to multiplication
- Flip the second fraction so it becomes its reciprocal (the numerator becomes the denominator and the denominator becomes the numerator)
Let's begin!
640 ÷ 2/5
We know that every number divided by 1 is itself, thus every numerator has an invisible 1 as its denominator. Now we can rewrite it as:
640/1 ÷ 2/5
First, keep 640/1. Then change the ÷ into a ×
640/1 × 2/5
Next, flip the 2/5 so the 5 is on top and 2 is on the bottom
640/1 × 5/2
And multiply across!
640 × 5 = 3,200
1 × 2 = 2
3,200/2 = 1,600
Your answer is 1,600!!
Hope this helps clear things up for you. Let me know if you any other questions :D
