Recursive equation calculation 7.54 + 12 out of 7 + 2.46 + 16 out of 7 (2.4-23 / 20) divided by 0.625 + 4 / 5 (1 / 15 + 3 / 49) * 15-45 divided by 49 2 / 5 * 11 / 15 + 0.4 divided by 15 / 4 Thank you~~~~

7.54+12/7+2.46+16/7=(7.54+2.46)+(12/7+16/7)=10+4=14（2.4-23/20）/0.625+4/5=（48/20-23/20)*5/8+4/5=5/4*8/5+4/5=14/5（1/15+3/49）*15-45/49=1/15*15+3/49*15-45/49=1+45/49-45/49=1
