mathcalc: A girl wants to knit a scarf 1 2/5 meters long. On Monday, she knits 1/4 of the scarf. On Tuesday, she knits another 45 cm. What fraction of the scarf has she knit in total?
Please no algebra
Hi mathcalc
We definitely do not need algebra for this one
2/5 = 4/10 = 0.4 so 1 2/5 metres is 1.4metre = 140cm
1/4 of the scarf is 140cm divided by 4 = 35cm
She has knitted a total of 35+45 = 80cm
The fraction she has knitted is the amount she has knitted divided by the total length that the scarf will be. 80/140 = 8/14 = 4/7
