15 = rate * 40
rate = 15/40
rate = 0.375 * 100% = 37.5%
0.98 as a unsimplified fraction would be 98/100. The simplified fraction would be 49/50 hope this helped
1. =4/16 which in simplified terms = 1/4
2. = 37/99 (find the lowest common denominator which is 99 then multiply them, then combine fractions then subtract them)
3. 2/25
4. 12/18 which simplified is 2/3
5. 5/15 which simplified = 1/3
Hope you understand that:)
