Answer:a) L.C.M OF 2,3,5 is 30
THEREFORE=60/30+15/30÷10/30-6/30
=60/30+15/30×30/10-6/30(DMAS)
=60/30+3/2-6/30
=60+45/30 -6/30(ADDITION FIRST THEN SUBTRACTION.
=105/30-6/30
=105-6/30
=99/30
=33/10
b)(3+1/2)÷(2-1/2)=L.C.M IS 2,=(6+1/2)÷(4-1/2)=7/2÷3/2=7/3
A unit rate compares a quantity to one unit of measure. You often see the speed at which an object is traveling in terms of its unit rate.
The speed of the water in the 3 feet radius is 25 feet per second.
You can write an equivalent expression with this knowledge by taking a two numbers, and multiplying both of them by a number. You can extract the number by taking the gcf of both of them, and dividing them both by it and putting the numbers in a parenthesis and multiplying the numbers by the gcf.<span />
