From the question it is given that,

Length of the skirt = 35*7/8cm = 287/8 cm

Dimension of hem = 3*1/8cm = 25/8 cm

Length of skirt, if hem is let down = ((287/8) + (25/8)) cm

= 312/8 cm

= 39 cm

"hello students welcome to lido homework i'm kislee praveen your maths tutor and today in this video i'm going to solve a math problem so let us read what the question says it says a skirt that is 35 7 by 8 centimeter long has a hem of 3 1 by 8 centimeter how long will the skirt be if the hem is let down so usually whenever there is a skirt okay suppose this is a skirt a part of is it is hemmed okay that means some part of the cloth is turned and it is hemmed okay so after the hemming is done this length is set to be 35 7 by 8 now suppose they remove this hem stitches it's like stitches they remove the stitches then this much part of it comes open and this hem length is how much three one by eight so three one by eight comes open three one by eight centimeter comes open so what will be the length of the skirt is what they have asked if the hem is let down so obviously we need to add this two numbers so let us do it quickly okay we can write it as length of the skirt after its hem is let down will be length of the skirt when hem is on that is 35 7 by 8 centimeter plus once it is taken off the hem is let down then 3 1 by 8 centimeter is added to that okay so now this is in mixed fraction form we'll convert it into improper fraction form so 35 into 8 becomes 280 plus 7 it is 287 by 8 plus 8 3's are 24 plus 125 by 8 since the denominators are same we just need to add the numerator 287 plus 25 which becomes 3 1 2 by 8 now when you divide it you get it as 39 centimeter so this is the final answer okay i hope it's clear if you still have any doubt put a message in the comment section and subscribe to our channel for regular updates bye "
