Answer:
1. Is simplest form.
2. Isn't simplest form.
3. Isn't simplest form.
4. Isn't simplest form.
5. Is simplest form.
Step-by-step explanation:
1. We can divide the denominator and numerator further by any number.
2. Both are multiples of 7 so we divide numerator and denominator by 7 : 7×5=35 & 7×7=49. Then we cancel both and the final answer comes 5/7.
3. Both are multiples of 6. So we divide numerator and denominator by 6 : 6×7=42 & 6×9=54. We cancel numerator and denominator by 6 and the final answer comes 7/9. *NOTE : We can use 2 also since both are even numbers but the process might be longer since we need to again further cancel and cancel until it comes 7/9.
4. For thus we need to use 2 only. There aren't numbers that can further divide. Final answer : 32/27.
5. No need to do. It's in simplest form.
