Please make this answer the brainiest~
Lan wants to run less than 7/12 miles. It says to find out a fraction with a denominator of 4 and which is less than 7/12.
Let's assume the required fraction to be x/4 such that x/4 is less than 7/12.
![\frac{x}{4} < \frac{7}{12} \\\\ 3*\frac{x}{4} < \frac{7}{12}*3 \\\\ \frac{3x}{4} < \frac{21}{12} \\\\ \frac{3x}{4} < \frac{7}{4} \\\\ 3x < 7](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B4%7D%20%3C%20%5Cfrac%7B7%7D%7B12%7D%20%5C%5C%5C%5C%203%2A%5Cfrac%7Bx%7D%7B4%7D%20%3C%20%5Cfrac%7B7%7D%7B12%7D%2A3%20%5C%5C%5C%5C%20%5Cfrac%7B3x%7D%7B4%7D%20%3C%20%5Cfrac%7B21%7D%7B12%7D%20%5C%5C%5C%5C%20%5Cfrac%7B3x%7D%7B4%7D%20%3C%20%5Cfrac%7B7%7D%7B4%7D%20%5C%5C%5C%5C%203x%20%3C%207%20)
So we must have multiples of 3's that should be less than 7, we have only two choices 3 < 7 or 6 < 7.
It means x = 1 or x = 2, and the required fraction would be 1/4 or 2/4.
2/4 is simplified to 1/2 and the question says to have denominator 4.
Hence, final answer is 1/4
Answer:
about 37, so probably B
Step-by-step explanation:
tg a = 3/4
tg a = 0.75
SOLUTION:
Amount added / Original amount × 100% = % increase
