math to endure the heat,firefighters wear protective gear that weighs about 40 pounds.If a suited-up firefighter weighs 220 pounds,how can you use mental math to find the firefighters weight without the gear?
Can you subtract 4 from 22?
yes, 22-4=18.
To find the firefighter's weight without the protective gear using mental math, you can subtract the weight of the gear (40 pounds) from the total weight of the suited-up firefighter (220 pounds).
Here's the mental math calculation:
220 pounds - 40 pounds = 180 pounds
So, the firefighter's weight without the gear is approximately 180 pounds.
