Frank had 25 meters of string. He cut off 480 centimeters that became tangled then used 98 centimeters to tie ul some tree branches. How many meters of string did Frank have left?
480 cm = 4.8 m
98 cm = 0.98 m
4.8 + 0.98 = 5.78
25 - 5.78 = ?
useful conversion: 1 meter = 100 centimeters
first, we convert the given with units of centimeters into meters:
480 centimeters = ? meters
to do this, we just divide 480 by 100 or:
480/100 = 4.80 meters
98/100 = 0.98 meters
then we add these two to get the total length that he cut and used:
4.80 + 0.98 = ?
now solve for this one~
after you have added them, you subtract this to the total length, which is 25 meters (given in the problem):
25 - (4.80 + 0.98) = ?
hope this helps~ :)
4.80+0.98=5.78-25=-19.22
To solve this problem, we need to convert the given lengths to the same unit of measurement (meters).
First, let's convert the 480 centimeters into meters. Since there are 100 centimeters in a meter, we can divide 480 by 100 to get the length in meters:
480 centimeters = 480 / 100 = 4.8 meters
Next, let's convert the 98 centimeters into meters using the same logic:
98 centimeters = 98 / 100 = 0.98 meters
Now we can add up the lengths that Frank cut off and used for tying:
4.8 meters (from cutting off) + 0.98 meters (from tying) = 5.78 meters
Finally, we subtract the total length that Frank cut off and used from the initial length of 25 meters:
25 meters - 5.78 meters = 19.22 meters
Therefore, Frank had approximately 19.22 meters of string left.
