Mercury orbits around the sun is 87 24/25 earth days. Venus orbits the sun in 224 7/10 earth days, and Mars orbits the sun in 68

pav-90 [236]

For this case we have the following mixed numbers:

$87 \frac {24} {25}\\224 \frac {7} {10}\\686 \frac {49} {50}$

We convert each mixed number into decimal:

Mercury orbits: $87 \frac {24} {25} = \frac {25 * 87 + 24} {25} = \frac {2175 + 24} {25} = \frac {2199} {25} = 87.96$

Venus orbits: $224 \frac {7} {10} = \frac {10 * 224 + 7} {10} = \frac {2240 + 7} {10} = \frac {2247} {10} = 224.7$

Mars orbits: $686 \frac {49} {50} = \frac {50 * 686 + 49} {50} = \frac {34300 + 49} {50} = \frac {34349} {50} = 686.98$

Answer:

Mercury orbits: 87.96

Venus orbits: 224.7

Mars orbits: 686.98
