The best thing to do is to find the cost of one sweet, and to do this, divide 42 by 7. 42/7= 6 Therefore, one sweet costs 6p. To find the cost of 8 sweets, you've got to multiply 6 by 8, and this gives you 54p. Therefore, 8 sweets cost 54p This is basically just finding unit rate and multiplying. <span>Hope this helps :)</span>
This is an irrational number because 3 is not a perfect square. sqrt4 = 2 and sqrt 1 = 1 So sqrt3 is Greater than 1 and less than 2. sqrt3 is approx. 1.7
