Ling can type 52 words per minute. She typed 364 words, which is 40% of the total number of words she needs to transcribe. How many minutes did Ling type? How many words does she have left to type?

Answer (3)

so 52 words per 1 minute
364 words per x minute 52:1 as is 364:x so divide 364 by 52 and get 7 she typed 7 minutes
so 40% means 40/100 or 4/10
so 364=4/10 divide 364 by 2 364/2=182=2/10 multiply 182 by 5 ( to make 2/10 into 10/10) and get 910=words total to type
BUT WE WANT TO FIND WORDS LEFT so 910-364=546 she has 546 words left to type

Ling can type 52 words. 52 words=1 minute 364 words is 40% 728 words is equal to 80% 182 words is 20%. Add the 80% and the 20% to equal 910 words as the full total. Ling has already been typing for 7 minutes, because the 364 divided by 52 is 7. So the 910 total take away the 364 she already typed = 546 words left to type. Ling has already been typing for 7 minutes, because the 364 divided by 52 is 7.
