Answer:
3/20 of the cover page is text about endangered species.
Step-by-step explanation:
We know that 3/8th of the page is text, and 2/5ths of that text is about endangered species.
So all we have to do is find out how much 2/5ths of 3/8ths are, which can be done simply via fraction multiplication.
3/8 * 2/5 = ?
For multiplying fractions, we multiply the top parts together, and then the bottom parts together. So 3/ 8 * 2/5 would be equal to (3*2) / (8*5). This gives us 6 / 40 which can be simplified to 3/20.
So 3/20ths of the cover page is about endangered animals.
Answer:
the original number is greater
Step-by-step explanation:
1. let 1x be your starting number
2. therefore, 0.5 * 1x = 0.5x ( amount after you decreased it by 50%)
3. then increase: 0.5x * 1.5 = 0.75x (amount after you increased it by 50%)
4. 0.75x < 1x (this means that the original number is larger than the one you decreased and then increased)
