Answer:
10 : 7
Explanation:
The given ratio is 80mm to 5.6cm. To simplify this ratio, we need to convert the measurements to the same units.
To convert 80mm to centimeters, we divide 80 by 10 since there are 10 millimeters in 1 centimeter. This gives us 8cm.
Now that both measurements are in centimeters, the simplified ratio is 8cm to 5.6cm.
We can simplify this ratio further by dividing both numbers by their greatest common factor (GCF). The GCF of 8 and 5.6 is 0.8.
Dividing 8cm by 0.8 gives us 10cm, and dividing 5.6cm by 0.8 gives us 7cm.
Therefore, the simplified ratio is 10cm to 7cm.
In summary, the simplified ratio of 80mm to 5.6cm is 10cm to 7cm.
