Answer:
3 more students need to sign up
Step-by-step explanation:
Let the equal number of students in 9 teams be x.
Total number of signed up students = 690.
Let t be the required number of students to be signed.
Therefore, 9x = 690+t.
This means, 690+t is a multiple of 9.
The least value of t to make 690+t, a multiple of 9 is 3 and hence,
= 77
Hence, 3 more students need to sign up and each of the 9 teams consists of 77 students.
Hi!
This question is about math.
<u><em>Least Common Factor 4 or 8: 8</em></u>
<u><em>Factors of 4 : 1, 2, 4 (prime factorization) (2*2)</em></u>
<u><em>Factors of 8: 1, 2, 4, 8 (prime factorization) (2*2*2)</em></u>
<u><em>Least Common Factor of a,b is the smallest positive number that divisible by both a and b.</em></u>
<em>Multiply each factor the greatest number of times it occurs in either 4 or 8.</em>
<em>Then multiply by the numbers.</em>
<em>Multiply each numerator by the same amount needed to multiply its corresponding denominator to turn it into the Least Common Factor of 8.</em>
<em>For 1/4 multiply the denominator and numerator by the 2.</em>
<em>Since the denominator are equal, combine the fractions.</em>
<em>Add the numbers 2+5=7</em>
Hope this helps! Thank you for posting your question at here on Brainly. Have a great day.
