What i learnt in math this week
This week i learnt how to change yards into inches. So first you have to take each number (4yrd, 6in, 2ft) and convert them separately. To convert each number we have to make an equation so we take the number we are converting (4yrds) multiplied by a fraction. In the numerator we put the number of inches in a yard (36in) and in the denominator we put how many yards go into an inch (1yrd). We then take pairings of units and cross them out and whatever unit doesn’t have a pairing should be the unit left in the answer (inches). Finally multiply straight across. We do the same thing for feet. Once you’ve converted all the numbers into inches add them together to get your answer.
What i learnt this week
This week i learnt how to simplify and express as a positive. You take the fraction and flip it to change the negatives to positives, but leave the exponents in the brackets negatives/positives. Then take the exponents outside of the brackets and multiply them but the expontents and the number inside the brackets. Then subtract the top exponents by the bottom and then multiply the ten by the sixty-four. Finally take the last negative and put it at the bottom of the fraction to make it a positive.
