Question in MASH Bath: Question Bank
The relationship between the frequency of an allele A, $x$, at a genetic locus in a diploid population and the fitness of a population with this frequency of allele A, $w$, is described by the function $w=ax^2+x(b-x)+c(b-x)^2$ . The aims are (a) ti simplify the algebraic expression, (b) calculate the fitness of a population with a given allele A frequency, and (c) calculate the allele A frequency when the fitness of the population is given.

Question in Skills Audits for Maths and Stats
Simplifying first is essential in terms of managing expressions that might need factorising.
-
Question in Skills Audits for Maths and Stats
Manipulate fractions in order to add and subtract them. The difficulty escalates through the inclusion of a whole integer and a decimal, which both need to be converted into a fraction before the addition/subtraction can take place.
-
Question in Skills Audits for Maths and Stats
A question to practice simplifying fractions with the use of factorisation (for binomial and quadratic expressions).
-
Question in Skills Audits for Maths and Stats
Simplify the sum of two algebraic fractions where spotting factorising of both numerators and denominators can reduce the work massively.
-
Question in Skills Audits for Maths and Stats
Simplify (qx+a)/(rx+b) +/- (sx+c)/(tx+d)
x is a randomised variable. a,b,c,d,q,r,s,t are randomised integers. a,b,c,d run from -5 to 5, including 0. q,r,s,t run from -3 to 3, and can be 0 if the constant term is nonzero, but are mostly 1.

Merryn's copy of Fractions/division and multiplication, different ways of presenting the same thing (non-algebraic) Ready to useQuestion in MESH
Students seem to not realise that $\frac{a}{b}\times c=c\times\frac{a}{b}=\frac{a\times c}{b}=\frac{c\times a}{b}=a\times c \div b=a\div b\times c=c\div b \times a \ne c \div (b\times a)\ldots $ etc. This question is my attempt to help rectify this.
