For this case we have the following mixed numbers:
[tex]87 \frac {24} {25}\\224 \frac {7} {10}\\686 \frac {49} {50}[/tex]
We convert each mixed number into decimal:
Mercury orbits:[tex]87 \frac {24} {25} = \frac {25 * 87 + 24} {25} = \frac {2175 + 24} {25} = \frac {2199} {25} = 87.96[/tex]
Venus orbits: [tex]224 \frac {7} {10} = \frac {10 * 224 + 7} {10} = \frac {2240 + 7} {10} = \frac {2247} {10} = 224.7[/tex]
Mars orbits: [tex]686 \frac {49} {50} = \frac {50 * 686 + 49} {50} = \frac {34300 + 49} {50} = \frac {34349} {50} = 686.98[/tex]
Answer:
Mercury orbits: 87.96
Venus orbits: 224.7
Mars orbits: 686.98
