Answer:
19/72
Step-by-step explanation:
To calculate the probability that a randomly-chosen child from this group likes either Chess or Swimming but not Football?
We already know the number that liked chess only which is 10, we have to solve for those that liked swimming only which is
8+7+16+x = 40
x which represent swimming only is
40-31 = 9
Thus probability = 10/72 + 9/72 = 19/72
To write 3.40 as a fraction you have to write 3.40 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.
3.40 = 3.40/1 = 34/10
And finally we have:
3.40 as a fraction equals 34/10 simplified we get: 3 2/5
The third angle would be 100 degrees
Explanation: 360-85-115-60= 100
Answer:
100 Rs 5 coins and 50 Rs 2 coins
Step-by-step explanation:
Bhairav collected Rs.600 in his piggy bank by putting in Rs.2 and Rs.5 coins. The number of Rs.5 coins are twice as many as Rs.2 coins
Let x be the number of 5 coins
and y be the number of 2 coins
The number of Rs.5 coins are twice as many as Rs.2 coins


Replace x with 2y


So 100 Rs 5 coins and 50 Rs 2 coins
