First you have to set the fractions with an equal denominator
hint: numerator/denominator
all of the denominators go into sixty
1/10=6/60
1/4=15/60
1/5=12/60
2/15=8/60
then you will have to add the numerators
(6+15+12+8)/60 = 41/60
simplify if possible but it's not necessary for this one
Hello! Grams would be the correct measurement. One kilogram is equal to about 2.2 pounds. If you cell phone weighed 113 kilograms it would be 249 pounds! The size of an adult!
One gram is about the weight of a paper clip, so it makes more sense for a cell phone to weigh 113 paper clips.
I hope this helps!
I believe it is 510 cm because a meter equals 100 cm so 210 cm times 2 equals 410 cm then multiply 45 times 2 and get 90 cm then add 410 plus 90 and get 510 cm.
